GrimmSpeed Up Pipe and Crosspipe Revisions!

Today marks the ending of a very long project for us here at GrimmSpeed. Over the last year we have been working on a large project to completely revamp and upgrade our existing Subaru exhaust pipe lineup. Our promise to you has been to continuously improve and over the last 4 years we have upgraded our exhaust pipe lineup multiple times to show you our commitment to that promise. This upgrade however is the biggest of all, a complete upgrade/redesign to the entire product...flanges, flex, tubing. We are very excited to bring our already top-of-the-line product even higher up the quality chain.

Design
We designed this Up Pipe using our in-house FARO Arm along with the latest and greatest Solidworks CAD software. This assures that we can offer you the most precise and best fitting Up Pipe on the market. In short, OEM exhaust manifold pieces are inconsistent so we used our reverse engineering hardware/software to scan countless OEM pieces to determine the range of best fitments for our aftermarket pipe. This allows us to be very confident that your flanges will be leak free and the Up Pipe will fit nicely.

Materials
Our Up Pipe has been made with beefy local raw materials. The flex joint is 321 Stainless Steel w/ an Interlocking Liner and tubing is a heavy duty 14 Gauge 304 Stainless Steel(competitors use thinner 16 GA) that has been CNC Mandrel Bent and finished up with a nice brushed finish. Our flanges are made out of 1/2" 304 Stainless Steel and are fully machined on all sides(competitors typically just laser cut flanges for cost reductions). We also put a nice bevel on the edge of the flange so you don't cut yourself. You're welcome. The insides of our flanges are "cut-back" to allow the pipe to rest inside the flange which gives you a nice flush mating surface thus allowing optimal flow through the pipe. Heck, we started as a Porting company after all....we take pride in exhaust flow quality through our pipes. All fabrication is completed by our Welder/Fabricator who is certified in Aerospace Welding...yeah, he knows his stuff. A bit of overkill using an Aerospace Welder you say? Well the Up Pipe is put through some very harsh environments so we wanted the best for the job.

Continually re-inventing heavy duty, it's what you can expect from GrimmSpeed™

I'm very excited to see you guys ripping around with these beasts on your cars!
